Specification of Letters Patent.

Patented March 1'1 Application filed July 9, 1907. Serial No. 382,852 I This invention has reference to improve,

ments in Windmill oilers, and itsohject is to provide on 011111;; device to be located on the Windmill head and to be operated from the ground or other convenient point.

The invention consists essentially in a suitable reservoir for the lubricating oil, with a force pump connected therewitharrangei to deliver the oil under pressure to the hearings to be lubricated whether such hearings are located above orhelow the lubricating device. .Pi'ovision is made ior regulating the len th of the stroke of the pump so that at eac stroke the pump may he made to deliver a reater or less quantity of oil, whereby, s'i'tnont changing the proportions of the parts, the device may be adapted to windmills of different sizes and requiring different quantities of oil for the hearings. l urthcrmore, provision is made for delivering dill'en ent quantities of oil to the diilei'ent bcerings in accordance with their needs by providing conduits of oitierent sizes, so that when the oil is put under pressure to be delivered to the various hearings some hearings will receive a larger quantity then others, depending on their size and need of lubrication.

The invention will be fully understood from the iollowin detailed description, taken in connection with the accomnenying drewing forming part of this specification, in which, the figure shows a side elevation,

Referring to the drawing, there is shot an upright stem oriented to be etteohed'by e. elem to the Secured to'tnis stem there is tsnlc or reservcir peoity and which is designed to contains supply of lubricating oil, This tank is secure-d to the stem 1 by means of straps 3 which may be bolted or riveted to the storm as desired, and after passin around the tank Z-msy be secured together y screws or bolts 4 at their outer meeting ends. At the upper end the tonic may be provided with a. suitable screwecs 5 coverlng Adjacent to t e tank is a pum cylinder 6 which'insy, if desired, be secure to the stem lower end of t uni and the letter is divided up by indies-t collar, and Where both are l nrtly in section, ot the improved Windmill in ricstor. 1

Between the eve 17 and e sin-s. nut 20 there is festupon the rod. l bracket 21 formed with on of such size as to slide upo he at the other end this hm. with an eye ".33 to which is last a 24 extending, if desired, to the gin" n point Within easy reach of on. 0')

Upon the stem 1 there is it collar M vided with s set-screw 26. This cells scljnstehle'to different points along llllQ/Stetli,

Z? or notches 28, or both, as may d When the indications are the ccis moved to the desired indication there fastened by the S-'t-SPXBW 126. the notches 28 are used the set-scrctv enter the desired notch on there h. d. the 1 simply movedto an indication and is caused to enter the notch and so collar 25 from accidentel'displecein Near the top of the pump chamber is in comm through a, passage 30 closed l 31 so arranged that oil may 1 chember-from the pump but csnno from the chamber to the pump. Leading; from this chamber are e number of pipes 32 for conducting the oil to the various perts to be lubricated. These pipes will be of different sizes, in accordance with the amount of oil to be delivered throu h them. For instance, e large journal Wil need more oil then a small one, or a shaft turning rapidly will need more oil than one turning more slowly. In this Way the oil may e dist retui 'tributed in accordance with the needof the several parts. The 'passage 30 as well. as the pipes 32 are located with reference to the casing 29 near the bottom of the latter so that'when oil is forced into the chamber in from time to time, and there is the casing 29 a certain amount of air is there imprisoned and o erates as an elastic cushion for continuing t e flow of oil through the pipes after thepump has ceased operating and the valve 31. has closed.

In the drawing the pumpcylinder 6 is shown very much larger in proportion to the reservoir 2 than would be the case in practies. The reservoir 2 might be made to con tain one ormore allons of oil, while the pump would at fulFstrbke not deliver more than two or three ounces of oil. Now, let it be supposed that the lowermost indication .on the stem 1 be ,guivalent to the delivery of one-half an ounce of oil, and the second indication be equivalent to the delivery of one ounce of Oil, and so on. In the drawing the collar 25 is shown coincident with the third indication, and, thepefore, the pumn is supposed to be set to deliver one and one-half ounces of oil. It will be understood, of course, that the amounts mentioned are only taken as examples and the device may be made to deliver oil in any series of quantities.

Let it be assumed now that the cord or Wire 24 is pulled downward. It will be seen thatthe piston-rod 15 and the piston 13 will participate in this movement, while the spring 18 will be extended and put correspondingly under stress. As the iston 13 descends the oil within the pump elow the piston passes upward through thes'ame and h t l 4.- low s i th t tl a y no vane i. r ,asumng a 1e piston-rod has been pulled down to the greatest extent, the cord 24 is released and piston upward. Under these conditions the valve 14 closes and the valve 10 opens so that oilflows into the cylinder 6 below the piston,

while the oil above the piston is lifted and flows through the opening 30 and by the valve 31 into the chamber in the casing 29. The pump thus acts as a force pump and the oil is driven out through the pipes by the pressure exerted thereon due to the power stored up in the spring 18.

By providing a force feed for the oil it is not necessary that the tank 2 or the outiet from the pump be located above the bear lugs to be lubricated, since the oil can be forced to bearings considerably higher than the pump. 7

With the structure described It essary to cause the flow of on to senses to connect the cord or wire 24 or the pistonrod to the throw-offmechanism for the windmill,,so that when the latter is moved to the inoperative position, which it is only occasionally, the pump may be operated to deliver oil to the bearings.

I claim 2- w 1 A windmill lubricator comprising a suitable reservoir, a pump, means for actuating the pump, a valved chamber into which the pump delivers, and. pipes leading from said chamber to the parts to be lubricated, the pipes and valve communicating with the chamber near its lower end.

2. A windmill oiler comprising a suitable reservoir, a force pump connected to the lower end of the reservoir and extending u ward alongside of the same, a chamber at tl ie upper endof the pump into which the oil is delivered by the pump, a valve between said chamber and the pump, and conduits leading from the chamber to the parts to be lubricated, the valve and conduits opening into the lower end of said chamber.

3. A windmill-lubricator comprising a suitable reservoir, a pump, and connections for deliverin oil from the reservoir to the parts to belui pump piston on its power stroke, a fixed guide adj acelnt to the pump rod carrying one end of the spring, a sliding connection be tween the guide and pump rod, and an adjustable stop on the guide in the path of the slide fast on the pump rod.

4. A windmill oiler comprising a suitable reservoir, a force pump connected therewith, a valved chamber connected with the delivery end of the force pump, conduits of difricated, a spring for moving the ferent capacities leading from the valved chamber to the parts to be lubricated, a supporting stem for the reservoir and pump, a spring carried by the stem and connected to the piston-rod and tending to move the um piston in the delivery direction, a

- racuet fast on the piston-rod and sliding on said stem, a connection from said bracket to a distant point of manipulatlon, and an adjustable stop carried by said stem in the path of the bracket traveling thereon.

In testimony that I claim the foregoing as my own, I have hereto aifixed my signature in the presence of two witnesses.
